A pencil which can contain fiberglass or brass brushes. As the brush is used it can be moved down by rotating the top of the pencil. Ideal for cleaning PCBs, copper tracks, etc. Refills are available separately.

I have a few of these now, one that I keep in the garage for spot sanding gravel chips on cars, and two in the house for cleaning up circuit board traces for soldering and one for cleaning mildew from bathroom grout. They also sell brass refills for these which work even better than the fiber glass for grout since the fiberglass pieces sometimes stick to caulking, etc.
